Etymotic ER-4PT

Etymotic ER-4PT : Etymotic ER-4PT vs. Etymotic ER-4S
In our linear test, which measures the response of the left and right earphones and then plots them against each other on a graph, the ideal is for the two lines on the graph to resemble one. A quick look at our test results in the slideshow reveals just how amazingly accurate the ER-4PT is. This is literally the best test result we've ever had for linear responseto prove it, we show how it is just slightly better than our former industry standardthe Etymotic ER-4S.

The Bose AE2 brings comfortable fit to a headphone pair that skips noise cancellation in favor of audio performance.
